The rapidly growing demand for portable devices brings new challenges for the research community. A great amount of prior research has focused on battery-life constraints of such portable devices. A cloud based thin client ...

Current portable devices e.g. cell phones, PDA's and laptops are mainly Wi-Fi capable. Users can make efficient use of these devices by running various applications. Among these, the Voice over Internet Protocol (VoIP) ...

We address the energy-efficient data redistribution problem in data-intensive sensor networks (DISNs). In a DISN, a large volume of data gets generated, which is first stored in the network and is later collected for further ...

The purpose of this research was to improve the communication technology for mobile computing devices. It focused on increasing the speed and reliability of data, voice, and video transmissions while away from a home or ...

In this correspondence, the ergodic channel capacity at a low signal-to-noise ratio (SNR) is established for variable-gain and fixed-gain amplify-and-forward (AF) relay systems in a generic noise environment. Long-term ...

Estimates of maximum amplitudes of conductor galloping are needed in order to determine appropriate phase-to-phase clearances on overhead lines. A new method for computing these estimates is presented. The method gives ...

The complex dielectric constant of sea water is a function of salinity at 21-cm wavelength, and sea-water salinity can be determined by a measurement of radiometric temperature at 21 cm along with a measurement of thermodynamic ...

Radio frequency identification (RFID) is used to identify, track, and manage tagged animate or inanimate objects automatically using wireless communication technology. A serious concern faced by RFID technology is the ...

There are great interests in understanding the manner by which the prime numbers are distributed throughout the
integers. Prime numbers are being used in secret codes for more than 60 years now. Computer security authorities ...

Distributed generation is one of the biggest changes that the power industry is facing with the mitigation of greenhouse gases and the smart grid initiative. With the presence of a communication infrastructure, it is ...

In this paper, a novel four symbols Finite Dimensional Modulation (4FDM) in three dimensional scheme with polarization diversity is presented that seeks to combine the advantageous features of phase shift-keying and ...

According to the U.S. Department of Energy (DOE ), “Smart grid generally refers to a class of technology people are using to bring utility electricity delivery into the 21st century, using computer-based remote control and ...

In this paper, we present a new block replacement algorithm for disk caches. Our Fuzzy Block Replacement Algorithm (fuzzy block-RA) utilizes nine fuzzy rules to pick out the block to be evicted when an I/O reference causes ...

Avoidance of collision between moving objects in a 3-D environment is fundamental to the problem of planning safe trajectories in dynamic environments. This problem appears in several diverse fields including robotics, air ...
